I am hypocritical about protein. The only current hesitation I have is toward octopus because of its intelligence. But pigs are also intelligent and I eat pork. However, if it is in a butcher case, there is no protein I won't eat for emotional reasons. Yet if I were to have to go to the farm and select an animal to be killed for my dinner, I would immediately become a vegetarian. So logic and absolute conviction obviously do not come into play. I am morally bankrupt.
re flavor and texture, I resort to my old maxim, "there are no bad foods, only bad cooks".
